A Danbury man has been arrested for allegedly breaking into his ex-girlfriend’s apartment and attacking several people with a utility knife. Police charged Jackson Ivan Ortega-Palacios on the 13th with burglary, criminal trespass, disorderly conduct and several counts of assault. Police say the 23-year-old cut the ex-girlfriend, as well as at least two other people, sending at least one to Danbury Hospital. In his arrest photo, the man's shirt is covered in blood and his face is scratched and has bruises. Ortega-Palacios was wanted on an outstanding warrant for two charges of risk of injury to a child stemming from allegations from last month.
